MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document, generated by wkhtmltopdf, contains multiple embedded URLs and a prominent external URI pointing to a potential download. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related lures reinforces the suspicion. While no scripts were explicitly extracted, the nature of the embedded URLs suggests an attempt to deliver a second-stage payload, likely related to game hacks or cheats.

Machine Learning

Heuristics 3

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
